Fujifilm's xD Picture card is the ultimate solution for the exciting new generation of compact digital cameras. The xD Picture card is one of the smallest, lightest flash memory cards available, yet it offers the fast read/write speed and high capacity that today's newest products require. Because of the need for increased capacity in a small form factor, Fujifilm has integrated high density MLC (Multi Level Cell) memory technology into the new xD architecture to make it possible to pack 1GB into an ultra-compact card. At 1GB, this Fujifilm xD Picture Card can approximately hold more than 1300, 600 and 400 images at 3, 6 and 12 megapixels, respectively. The new Type M is compatible with most USB card reader/writers, allowing digital images on the card to be read directly via a computer USB port without requiring a connection to a digital camera. When an xD Picture Card is inserted into any of these reader/writers, the card essentially becomes a portable hard drive for easy transfer of images, data, and voice files from one computer to the next. Some readers/writers may require firmware upgrades to take advantage of this capability.
